Show HN: RapidCam – Browser-based, parametric 2D CAD/CAM app for CNC and laser

- RapidCam is a new browser-based 2D CAD/CAM tool designed for CNC milling and laser cutting. "CAD" (computer-aided design) lets you draw shapes; "CAM" (computer-aided manufacturing) generates machine toolpaths from those drawings. - "Parametric" means dimensions can be changed as named variables, so the design updates automatically—a key feature of professional tools like Fusion 360 or SolidWorks. - The app runs entirely in a web browser (no install), which is unusual: most capable CAM software is desktop-only. - CNC (computer numerical control) machines cut material by following coordinate instructions; laser cutters / engravers use a focused beam. Both require precise toolpath planning. - This targets hobbyists, makers, and small shops who find existing options expensive (Fusion 360), complex, or not browser-based.
